What we are going to do is design a simple 4-bit computer at the primitive logic gate and flip-flop level and then implement it in the technology of our choice I’ve often wondered what would happen if ...

The registers inside the CPU, the machine code instruction set, and the ways in which the instructions interact with the registers and status flags are all intertwined. As you may recall, one of my ...

Scott Baker] is at it again and this time he has built a 4-bit single board computer based on the Intel 4004 microprocessor. In the board design [Scott] covers the CPU (both the Intel 4004 and ...

Today’s CPUs are so advanced that they might as well be indistinguishable from magic, right? Wrong! Fundamentally, modern CPUs can be understood logically like any other technology, it’s just that ...

Rockwell had introduced its PPS-4, a 4-bit processor in 1972, and Texas Instruments was working on a chip of its own. And, unknown to Intel, Motorola was working on its 6800 8-bit processor, which ...

An earlier logic chip used as a building block for CPUs. Bit slice processors used arithmetic logic units (ALUs) that typically came in 4-bit increments, although 1- and 2-bit devices were also made.

Wish your PC booted up faster? Well, if you think your computer has a sluggish startup time, how about waiting the best part of a week for the machine to boot? That’s the length of time a Linux PC ...

With the rollout of the Samsung Note 4 already underway, the concerns that Samsung makes one model with a Qualcomm processor and one model with a Exynos processor is rearing its ugly head again, just ...
